PIPE OR NUT WRENCH.

SPECIFICATION forming part of Letters Patent No. 599,578, dated February 22, 1898. Application filed February 20, 1897. Serial No. 624,494. (No model.)

To a whom it may concern: Be it known that I, WILLIAM T.WILLIAMS, a citizen of the United States, residing at Birmingham, in the county of J efferson and State of Alabama, have invented certain new and useful Improvements in Pipe or Nut Wrenches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. p

This invention relates to that class of wrenches adapted for-use either as a nut or pipe wrench, and has for its object to provide a wrench whereby the acting ,faceof the moving jaw may adjust itself to various angles relative to the fixed jaw for adapting the same for use as a pipe-wrench, and whereby all springs and other small parts usually employed which are liable to break or get out of order are dispensed with.

The invention consists in forming the recess for the adjusting-nut in circular or cylindrical form with the opening for the screwshank of the moving jaw made oblongin form, and with an operating-nut made in ball or spherical form, whereby while permitting the moving jaw to adjust itself to various angles relative to the fixed jaw for different kinds of work all lost motion is prevented, and in certain other novel features, all as hereinafter explained.

In the accompanying drawings,-Figure 1 is a perspective view of the improved wrench. Fig. 2 is a side elevation with the fixed head or jaw in section and showing the threaded shank of the moving jaw also in section. Fig.

3 is a section on the line 3 3, Fig. 2.

The fixed jaw A is provided with the usual serrated face a for adapting the wrench for use as a pipe-wrench, and the rear of the jaw isprovided with an enlargement or head B, havingits rear face preferably made in curved form to produce an ornamental configuration andin which head is formed the nut-recess B, which is made in circular or cylindrical form, substantially as shown. The openings 0 for the passage of the screw-shank O of the moving jaw are made in elongated form and tapering inwardly, so that while the side face of the shank shall be closely embraced by the head said shank is free to work in the head forward and backward to permit the gripping-face of the moving jaw to assume different angles relative to the fixed jaw.

The nut D is made in spherical form to closely fit the recess B, and it will be readily seen that while it permits the free movement of the jaw, as before described, it prevents all lost end motion.

The shank A of the fixed jawis screwthreaded, as shown at A, and the handle is provided with a female screw-thread to permit the lengthening or shortening of the wrench.

Having now described the invention, what is claimed as new, and sought to be secured by Letters Patent, is v 1. In a combined pipe and nut wrench, the fixed slotted head through which the shank of the moving jaw reciprocates, in combination with the adjusting-nut made substantially in spherical form, substantially as and for the purpose set forth.

2. In a combined pipe and nut wrench, the fixed head provided with the circular nut-recess and the openings for the passage of the moving-jaw shank made in elongated form, the movable jaw and its screwthreaded shank, in combination with the spherical nut, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM T. WILLIAMS.
